(under subclass 47) Process wherein a chemically reactive material is employed in or on the body of casting material itself to raise or maintain the temperature thereof.
(1) Note. Applying an open flame to the casting material is not considered a chemical reaction for this subclass.
(2) Note. The reactive heating does not have to be in the mold cavity but may be in some portion of the mold body.
